DAVID FERGUSON, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TOOLIVER G. FERGUSON.

COKE-DRAWER.

SPECIFICATION forming part of Letters Patent N 0. 707,686, dated August26, 1902. Application filed April 1,1901. Serial No. 53,773. (No model.)

To aZZ 1071,0712 it nmy concern:

Be it known that I, DAVID FERGUSON, a citizen of the United States,residing at Pittshurg, in the county of Allegheny and State ofPennsylvania, have invented or discovered new and useful Improvements inCoke- Drawers, of which the following is a specification.

In the accompanying drawings, which make IO part of this specification,Figure I shows in perspective and partly in section the generalarrangement of a coke-oven coke-drawer, the coke-conveyer plates beingomittedand car below the horizontal planeof said conveyer.

I5 Fig. II is a detail side elevation of endlesschain conveyer, showingplates attached to said chain. Fig. III is a detail vertical sectionshowing the movable rest for the reachrod of the coke-drawer. Fig. 1V isan enlarged broken perspective showing the drum with its clutch and thereach-rod with its rest.

The general object of my invention is to provide means for theexpeditious removal and handling of coke from the oven to itsdepository.

Heretofore in the withdrawal of coke by hand-power from the oven thereach-bar was inserted, the end blade worked down behinda small sectionof the coke,thereby.loosening that portion andthen withdrawing it,-andthe r operation repeated until the contents were withdrawn.

I have devised in this invention means that are applicable to all stylesof ovens. Besides, the operator has perfect control in the oven over theinsertion, locating, aifixing, and withdrawal of the coke-drawer.

In the accompanying sheet of drawings, 1 represents a truck mounted onwheels 2 2, said wheels being mounted on rails 3 3.

4 4 are extension-supports for sprocketwheels 5 5, said wheels beingsecured to shafts 6 and 6, which revolve in bearings in supports 4 4.Shaft 6 is the drivingshaft and can get its power from any suitablesource. 7 7 are endless chains. Mounted on and secured to said chainsare plates 8 8.

9 is a sprocket-wheel secured to shaft 6. 10 is an idler sprocket-wheelconnected by endless chain 11 to wheel 9.

12 is ashaft secured to standards 13 13. Secured on shaft 12 iswinding-drum 14.

15 is a lateral movable collar keyed on shaft 12 and having projection16, which engages the slot 17 of the sprocket-wheel 10.

18 is a shifting-barloosely secured between flanges 15 15' on the collar15 and secured to the cross-head 19 by means of a loose pin 20, wherebythe shifter-handle when moved laterally will through its-fulcrum-pin 20move the collar along the shaft until the projection 16 enters the slot17.

21isachain or flexible device Wound around the drum 14: and its endssecured to looselymounted lugs 22 and 23 on reach-rod 24:. Collars 2525,only one of which is shown, are rigidly secured to the reach-rod 24.

26 represents the end blade of the reach'rod.

27 is a forked bearing and capable of a movement along horizontalsupport 28, lying 7o beneath the drum 14 and secured to standards 13 13.The forked bearing is secured to support 28 through slot 29 by means ofnut 30. (Shown in Fig. III.)

The reach-rod 24 has secured thereto the cross-handle 33, by' which itis pushed or driven toward the oven.

In Fig. III, I have shown a movable rest 31, supported between rolls 3232, carried on the inner sides'of the standards 13 13. The downwardprojections 22 and 23 on lugs 22 and 23 act as means to push the resteither forward or backward.

In the initial operation of my invention and after the truck 1 is inalinement with the oven-opening 36 reach-rod 24 would be revolved untilthe blade pointed upward. The operator would then push the reach-rodinto the oven over the coke to the desired point. He would then by meansof the leverage 9o gained by the handle-bar and the rods fulcrum inforked bearing 27 turn the blade in the heated coke and force it bylateral pulls on the handle-bar into position behind the coke. It isthen ready to be withdrawn. 5 Shifting-bar 18 is pushed over untilprojection 16 of collar 15, slidin'g'ona horizontal key, engages slot 17of loose sprocket-wheel 10. The engagement causes shaft 12 andwinding-drum 14 to revolve, winding the chain 21, so that it pulls onthe lug 22, which in turn pulls through the collar on the inner end ofthe reach-bar, gradually drawing the bar and coke outward until theblade pushes the coke upon the chute 34:. Shiftingbar 18 is thenreversed, stopping the revolutions of shaft 12. When the rod 24 has beenpushed into the oven, the projection23' has also pushed in the rest 31,so that the heavy forward end of the rod may rest thereupon while theoperator is moving it from side to side or turning it over or otherwiseoperating it. It will be seen that the handle 33 is very close to thefulcrum of the rod 24 when the latter is shoved into the oven,making itvery hard to hold up the inner end and at the same time properlyoperateit. When the rod is withdrawn, the projection 22 pushes the rest 31 backto its normalposition out of the way of the coke in front of the blade26. The op- 1 eration can be repeated if it is desirable to make morethan one draw to an ovens charge. The coke slides down chute 34 andfalls upon plates 8 8, which carry it forward and deposit it in the car35. Since the plates 8 8 do not abut against each other,they affordmeans for screening or freeing the ashes and small pieces of coke fromthe general bulk of coke before reaching car 35.

Instead of one end of chain 21 being secured to the reach-bar at lug 23it could be secured to the drum, thereby winding directly upon the drumfrom the end secured at lug 22.

Having described my invention, I claim 1. Ina coke-drawer, aframe, adrummounted therein, a reach-rod, a flexible device op-.

eratively connecting the drum and the rod, a conveyer, disconnectibledriving connections between the conveyor and the drum, and means securedto the rod to which power may be applied for driving the rod and thedrum when the rod is entering the coke-oven.

2. In a coke-drawer, a frame, a drum mounted therein, a support having aslot parallel to the axis of the drum, a swiveled forked bearingadjustable in the slot, an axially-rotatable reach-rod in the forkedbearing, a flexible device on the drum and secured to the reachrod, andmeans on the latter to which power may be applied for driving the rodand the drum when the rod is entering the coke-oven.

3. In a coke-drawer, a frame, a windingdrum therein, a support beneaththe drum, a swiveled bearing adjustable on the support independently andlongitudinally of the axis of the drum, a reach-rod seated in thehearing, a flexible device operatively connecting the drum and the rod,and means for operating the drum.

4. In a coke-drawer, a frame, a windingdrum, and a support independentlymounted therein, a swiveled forked bearing adjustable along the supportindependently and longitudinally of the axis of the drum, anaxiallyrotatable reach-rod seated in the forked bearing, a flexibledevice wound on the drum and having its ends fastened to the reach-rod,and means for moving the rod longitudinally.

5. In a coke-drawer, a frame, a drum and a slotted support independentlymounted therein, a swiveled forked bearing adjustable in the slot of thesupport independently and longitudinally of the axis of the drum, anaxially rotatable reach rod seated in the forked bearing, a flexibledevice wound on the drum, and having its ends fastened to the rod, andmeans for longitudinally moving the rod.

6. In a coke-drawer, a reach-rod, a fulcrumsupport therefor, and aslidable rod-rest below the same.

7. In acoke-drawer, a reach-rod, a fulcrumsupport therefor, a slidablerod-rest below the rod, and means on the rod for sliding the rest.

8. In a coke-drawer, a reach-rod, a support therefor, a slidablerod-rest and projections on the rod for sliding the rest.

9. In a coke-drawer, the combination of a rotatable reach-rod, said rodhaving a downwardly-projecting end, a support for the rod, a movablerod-rest below said rod, a drum, a chain secured to said drum and to theforward end of said reach-rod, and means for withdrawing said rod.

10. In a coke-drawer, a power-driven endless conveyer, a winding-drum, adriving device loose thereon and geared to the conveyer, a collarslidably held thereon, means for interlocking and disconnecting saiddevice and collar, a reach-rod, a flexible device secured to said rodand wound on the drum, a blade on the rod, and a chute leading to theconveyor.
